本発明は、液晶表示装置の解体方法に関するものである。
The present invention relates to a method for disassembling a liquid crystal display device.
近年、薄型、大型化に適した表示装置として液晶ディスプレイパネルを用いた液晶テレビやプラズマディスプレイパネルを用いたプラズマテレビなどの薄型テレビが、大量に生産され、販売も拡大している。これに伴い、使用済み薄型テレビの廃棄台数も徐々に増加しつつある。環境問題および省資源の観点から、使用済み薄型テレビの各種部材、材料を再利用できる形態で解体する体制の整備が重要となってきており、効率的な解体処理方法が求められている。
In recent years, thin televisions such as a liquid crystal television using a liquid crystal display panel and a plasma television using a plasma display panel as a display device suitable for being thin and large have been mass-produced and their sales are expanding. Along with this, the number of used flat-screen televisions discarded is gradually increasing. From the viewpoint of environmental problems and resource saving, it is important to establish a system for disassembling various components and materials of used flat-screen televisions in a form that can be reused, and an efficient disassembly processing method is required.
例えば、液晶表示装置に使用されている各種部材、材料を再利用するためには、材料の種類ごとに解体、分別する必要がある。また、環境負荷物質などを含む材料については適切な処理をする必要がある。
For example, in order to reuse various members and materials used in a liquid crystal display device, it is necessary to disassemble and separate each material type. In addition, it is necessary to appropriately process materials including environmentally hazardous substances.
従来、液晶表示装置を解体する方法として、例えば、特許文献１に開示された方法が知られている。この特許文献１には、バックライトを備える廃液晶表示装置を解体する方法が開示されている。具体的には、廃液晶表示装置からキャビネットを取り外す工程と、キャビネットを取り外した廃液晶表示装置から制御基板を取り外す工程と、バックライトを取り外す工程とを有する廃液晶表示装置の解体方法が開示されている。
Conventionally, as a method for disassembling a liquid crystal display device, for example, a method disclosed in Patent Document 1 is known. This Patent Document 1 discloses a method of dismantling a waste liquid crystal display device having a backlight. Specifically, a method for disassembling a waste liquid crystal display device including a step of removing a cabinet from the waste liquid crystal display device, a step of removing a control board from the waste liquid crystal display device from which the cabinet has been removed, and a step of removing the backlight are disclosed. ing.
液晶表示装置のバックライトに使用されている蛍光管には水銀が封入されており、また、蛍光管自体が非常に破損しやすい構造となっているため、解体作業中に破損したり、回収搬送中に破損したりすることがある。破損すると、解体にあたっている作業者が水銀を吸ってしまう危険がある。
The fluorescent tube used in the backlight of the liquid crystal display device is filled with mercury, and the fluorescent tube itself has a structure that is very susceptible to damage. It may be damaged inside. If it breaks, there is a risk that the worker who is dismantling will inhale mercury.
本発明は、液晶パネルおよびバックライトを有する液晶モジュールを解体する前に、液晶モジュールの液晶パネル表面側よりＸ線を照射する。このＸ線の照射により、発生する蛍光Ｘ線を検出して液晶パネルに含まれる元素を分析するとともに、液晶モジュールの裏面側に後方散乱もしくは透過するＸ線を検出して、バックライトの種類および状態を判別する。その後、判別されたバックライトの種類および状態に基づいて、液晶モジュールの解体方法を決定する。
In the present invention, X-rays are irradiated from the liquid crystal panel surface side of the liquid crystal module before disassembling the liquid crystal module having the liquid crystal panel and the backlight. This X-ray irradiation detects fluorescent X-rays generated and analyzes elements contained in the liquid crystal panel, and detects back-scattered or transmitted X-rays on the back side of the liquid crystal module, Determine the state. Thereafter, a disassembly method of the liquid crystal module is determined based on the determined type and state of the backlight.
以下、本発明の一実施の形態における液晶表示装置の解体方法について、図面を参照しながら説明する。
Hereinafter, a method for disassembling a liquid crystal display device according to an embodiment of the present invention will be described with reference to the drawings.
図１は本発明の一実施の形態における液晶表示装置の液晶モジュールの構成を示す分解斜視図である。図１に示すように、液晶モジュール１は、液晶パネル２、光学シート３、バックライト４およびそれらを収容するための前面外枠５と後面外枠６とを組み合わせて構成されている。また、前面外枠５と後面外枠６はビスなどで締結されている。バックライト４は複数本の蛍光管で構成されており、このバックライト４の上部には、光学シート３、液晶パネル２の順番で各々が配置されている。
FIG. 1 is an exploded perspective view showing a configuration of a liquid crystal module of a liquid crystal display device according to an embodiment of the present invention. As shown in FIG. 1, the liquid crystal module 1 is configured by combining a liquid crystal panel 2, an optical sheet 3, a backlight 4, and a front outer frame 5 and a rear outer frame 6 for housing them. The front outer frame 5 and the rear outer frame 6 are fastened with screws or the like. The backlight 4 is composed of a plurality of fluorescent tubes, and the optical sheet 3 and the liquid crystal panel 2 are arranged in this order on the backlight 4.
次に、このような液晶表示装置において、製品寿命を迎えた使用済み液晶表示装置を解体するための方法について説明する。
Next, a method for disassembling a used liquid crystal display device that has reached the end of its product life in such a liquid crystal display device will be described.
図２は、本発明の一実施の形態における解体方法において、液晶モジュール１の検査装置を示す説明図である。
FIG. 2 is an explanatory diagram showing an inspection device for the liquid crystal module 1 in the disassembling method according to the embodiment of the present invention.
まず、液晶表示装置から液晶モジュール１を取出し、液晶パネル２側を下面にして搬送装置１０上に設置する。この搬送装置１０を駆動させることにより、図２に示すように、液晶モジュール１が検査部に移動する。このとき、Ｘ線漏洩を防止するために、上方よりＸ線遮蔽筐体１１が下降する。

By driving the transport device 10, the liquid crystal module 1 moves to the inspection unit as shown in FIG. At this time, in order to prevent X-ray leakage, the X-ray shielding housing 11 is lowered from above.
次に、検査部において、液晶モジュール１の下方にあるＸ線源１２より、液晶パネル２に向けＸ線１３を照射する。Ｘ線１３を照射することで、蛍光Ｘ線１４が発生し、この蛍光Ｘ線１４をＸ線検出器１５で検出する。そして、Ｘ線検出器１５で検出した蛍光Ｘ線１４に基づき、分析装置１６により液晶パネル２のガラス中の元素を分析する。この分析では、環境負荷物質元素、例えばヒ素やアンチモンなどの含有有無を判断するとともに、ガラス成分の元素とその割合を分析する。そして、この分析に基づいて、ガラスの種類を識別する。

Then, based on the fluorescent X-ray 14 detected by the X-ray detector 15, an element in the glass of the liquid crystal panel 2 is analyzed by the analyzer 16. In this analysis, the presence or absence of an environmentally hazardous substance element such as arsenic or antimony is determined, and the elements of the glass component and the ratio thereof are analyzed. And based on this analysis, the kind of glass is identified.
また、液晶パネル２にＸ線１３を照射することで、液晶モジュール１の裏面側にもＸ線１３が散乱もしくは透過する。これらの後方散乱もしくは透過したＸ線１７を検出センサ１８で検出する。この検出センサ１８で検出したＸ線１７に基づき、画像処理装置１９で画像処理してモニター２０により観察し、バックライト４の種類（蛍光管もしくはＬＥＤ等）を判断し、バックライト４としての蛍光管の割れを判断する。
Further, by irradiating the liquid crystal panel 2 with the X-rays 13, the X-rays 13 are scattered or transmitted also on the back side of the liquid crystal module 1. These backscattered or transmitted X-rays 17 are detected by a detection sensor 18. Based on the X-rays 17 detected by the detection sensor 18, image processing is performed by the image processing device 19 and observation is performed by the monitor 20, the type of the backlight 4 (fluorescent tube or LED) is determined, and the fluorescence as the backlight 4 is determined. Determine if the tube is broken.
そして、以上のような検査結果に基づき、液晶モジュール１に使用されている材料、バックライト４の種類や割れなどの状況を把握し、この把握した結果に応じて、以降の解体プロセスを決定する。具体的には、バックライト４に使用されている蛍光管が破損している場合には、解体時に作業者が水銀を吸い込まないように、保護具を装着して作業するなどの適切な対応を行う。また、液晶パネル２のガラス材料の種類に応じて、分別を行う。

Do. Further, sorting is performed according to the type of glass material of the liquid crystal panel 2.
以上のように本発明の一実施の形態によれば、液晶モジュールを解体する前に、液晶パネルユニット表面側よりＸ線を照射し、発生する蛍光Ｘ線によりパネルガラスに含まれる元素を分析する。そして、環境負荷物質の含有有無の判定や、パネルガラスの成分元素とその割合を分析して、ガラスの種類を識別するので、後工程での適切な処理が選択可能となり、解体作業の効率化を図ることができる。また、後方散乱もしくは透過したＸ線に基づいて、バックライトの状態を画像により観察し、バックライトの構造や種類、バックライトに使用している蛍光管の割れの有無を判断するので、後工程での適切な処理が選択可能となり、解体作業の安全性を確保することができる。
As described above, according to one embodiment of the present invention, before disassembling the liquid crystal module, X-rays are irradiated from the surface side of the liquid crystal panel unit, and the elements contained in the panel glass are analyzed by the generated fluorescent X-rays. . And, by determining the presence or absence of environmentally hazardous substances and analyzing the component elements and ratios of panel glass to identify the type of glass, it is possible to select an appropriate process in the subsequent process, making the dismantling work more efficient Can be achieved. In addition, based on backscattered or transmitted X-rays, the state of the backlight is observed by an image, and the structure and type of the backlight and the presence or absence of cracks in the fluorescent tube used in the backlight are determined.
